AUGUST HwLEIPERT, OF NEW YORK, N. Y., ASSIGNOR TO THE RUBBER SHOCK INSU- LATOR CORPORATION, OF WILMINGTON, DELAWARE, A CORPORATION OF DELA- Application filed March 17, 1928.

The present invention relates to devices for mounting electrical conductors which are suspended under considerable tension particularly where the conductors are subject to wind, rain and other natural elements. In

the application of William R. Edson, Serial No. 116,521, filed June 17, 1926, there is described a mounting for electrical conductors wherein the rigid cross arm or supporting means carries a housing containing a yielding non-metallic material such as rubber.

Secured within this material a bracket is carried which supports the wire. Relative movement between the wire and supporting arm is resisted yieldingly by the rubber contained within the housing. Connections of this character, wherein relative movement between the wire and housing is permitted,

are extremely desirable and jlengthen the life of the insulation considerably, as well as protecting the wire from crystallization. The continual chafing and vibration caused by wind, temperature changes, pole vibration and change in temperature of the wire due to variations of current carried thereby, etc., has required considerable attention in old forms of mountings, and the im roved mountings have been found to reduce t 1e deleterious effects of the above elements quite materially.

'This invention relates to a wire mounting of the character described in the above application, but embodies an improved form which is designed to accommodate, more completely, the various reactions which take place in the wire. It combines with a high tension insulator of the desired form a yielding mounting which is secured to the high tension insulator by a pivotal connection, thereby permittin a degree of movementof the insulator bodi y with respect to the wire and non-metallic yielding means.

Further objects and advantages will ap pear as the description proceeds and reference will now be had to the accompanying drawings, wherein:

Figure 1 is a view in section of one form of the mounting.

Figure 2 is a view in section showing a sli htly modified form.

eferring particularly to Figure 1, a 1nd1- cates a connecting eye bolt ada ted to be secured to the cross arm of a po c, it bein embedded in a high tension insulator b o MOUNTING FOR ELECTRIC CONDUCTORS.

suitable form. At the other extremity of the high tension insulator b, a depending supporting member a is carried having a sleeve through which stub shaft d may pass. A two-part housing 6 is provided with a flanged extension e having apertures to receive the ends of the stub shaft d, thereby permitting a degree of pivotal movement of the housing 6 with respect to the supporting member 0. lVithin the housing 0, a block of yielding non-metallic material f is carried, bolts 6 securing the lower ends of the housing together and placing the non-metallic yieldin material under compression.

The yieiling material I is formed to receive an end of a wire bracket 9, suitable seats 9' being formed on the bracket to receive the engaging portions of the block of yielding non-metallic material. The lower end of the bracket 9 is provided with a split housing consisting of upper and lower sections 9 and g res ectively. The high tension wire passes t rough an annular block of rubber or other yielding non-metallic material i which is carried between the housing members 9 and g A bolt in securely clamps the sections together and exerts a desired degree of compression upon the annular member a.

In the form shown in Figure 2, the housing Z is formed with a closure Z which is secured to the housing 6 by means of bolts Z engaging the flanges l and Z on the respective members Z and Z. Independent blocks of yielding non-metallic material m and m are carried within the housing Z and the high tension wire j is mounted within the annular block 71 similar'to the form shown in Figure 1. The split housing sections g and g are secured to a bracket n. which is provided at its upper end with a T-shaped head having extensions 12- and 11?. Each extension is provided with seats n and n which enga e the respective blocks m and m.

rom the above, it will be seen that the wire is supported within the brackets g or n and chafing between these members is prevented through the connection described. The bracket, in turn, is mounted yieldingly within the housin e or Z which is pivoted to the high tension insulator b. By virtue of this mounting, the wire is permitted a desired degree of movement in every direction without causing injurious effects thereon.

Although the invention has been described with respect to the specific forms shown, it is notto be limited, save as defined in the appended claims.

I claim as my invention:

1. A mounting for electric conductors comprising a housing, means to secure the housing to a support, yielding non-metallic material in the housing, a bracket extending within the housing and mounted within the material, yielding non-metallic material carried by the bracket, and means to mount an electric conductor in the last named material.
